About this file
This is a Polarized Light Microscopy (PLM) Bulk Asbestos Analysis Report prepared by Micro Analytical Services, Inc. for Cherokee Nation 35, LLC, analyzing samples from Building 633 at Fort Bliss, Texas. The report details asbestos testing for six different sample locations (633-01 through 633-06), using EPA-approved testing methods, with samples collected on 04/10/2025 and analyzed on 04/18/2025. None of the tested samples contained asbestos; the materials consisted primarily of black fibrous roof shingles with pebbles (composed of 20% fibrous glass, 40% aggregate, 40% asphalt) and black fibrous penetration materials (10% cellulose, 90% asphalt).
The laboratory is accredited by the National Institute of Standards and Technology under the National Voluntary Laboratory Accreditation Program (NVLAP) and licensed by the Texas Department of State Health Services. The analysis was conducted using polarized light microscopy with dispersion staining, following EPA methods for determining asbestos in bulk building materials. The report notes that some materials, particularly floor tiles, may contain asbestos fibers too thin to be detected by this method, and the samples will be retained for 30 days after analysis.
